First, convert the mixed fractions into improper fractions:

3\frac{1}{8} = \frac{8(3) + 1}{8} = \frac{25}{8}

1\frac{2}{3} = \frac{3(1) + 2}{3} = \frac{5}{3}

Next, divide a fraction by multiplying by the reciprocal:

\frac{25}{8} ÷ \frac{5}{3} = \frac{25}{8} x \frac{3}{5} = \frac{25(3)}{8(5)}

Lastly, simplify the fraction:

\frac{5(3)}{8} = \frac{15}{8}

Answer: \frac{15}{8} = 1\frac{7}{8}

Please help! Will pick Brainliest for the right answer!!!

Answer:

3/5

4/3

2/1

3/1

Step-by-step explanation:

turn them to ratios and fractions and try to simplify

3/5=3/5

4/3=4/3

2/1=2/1

6/2=3/1

so put the end results in order

so all of them have a bigger numerator than denominator, except one. 3/5. Thats the slowest one.

4/3 isn't quite 2 wholes, but 2/1 is, so 4/3 is second last and 2/1 is second.

3/1 is the first.

Compare and contrast the pairs of quadrilaterals based upon properties of sides and angles
icang [17]

Answer:

See below.

Step-by-step explanation:

1. The opposite sides of a parallelogram and a rectangle are equal.

All angles in a rectangle are right angles.  A parallelogram has 2 pairs of opposite equal angles, the angles are not necessarily right angles.

A rectangle is a special form of a parallelogram.

Choose the graph that matches the following system of equations:
Lelu [443]
In intercept form, the equations are
.. x/(-5/8) +y/(-1) = 1
.. x/(3/7) +y/(-1) = 1

The first line has intercepts (-5/8, 0) and (0, -1).
The second line has intercepts (3/7, 0) and (0, -1)

In the second graph, the (blue) line with positive slope has an x-intercept greater than 1/2. Neither line matches that. The intercepts match those of the first graph.
